Gas boiler drum barrel ring mainly longitudinal seam submerged arc narrow gap submerged arc welding, electroslag welding; fall pipe used mainly saddle submerged arc welding and manual arc welding; bassoon mainly saddle seat and submerged arc welding SMAW; other accessories using GMAW and SMAW. Headers barrel girth welding mainly narrow gap hot wire TIG welding and submerged arc welding; bassoon seat mainly cored wire gas shielded welding and manual arc welding (flux cored wire for no material); heating surface base mainly bore welding and manual arc welding. Gas boiler thick-walled container for narrow gap seam SAW is a high quality, high efficiency, low consumption of welding methods. Has been promoting the use of submerged arc narrow gap in China's major boiler, chemical machinery and heavy machinery factories, nearly 20 years of practical experience shows that narrow gap SAW is really the best choice for butt welding of thick-walled container. To further enhance the efficiency of SAW narrow gap at home and abroad to launch tandem arc double wire narrow gap SAW technology and equipment, but has not been widely popularized.
